LED Chips, on the Cheap LED bulbs have long been lauded as an energy-efficient alternative to incandescent bulbs. But LED, or light-emitting diode, bulbs are expensive to produce, which has kept ...

Company says it has demonstrated the production of LED light chips on silicon, an effort that could ultimately result in cheaper energy-efficient light fixtures. Martin LaMonica is a senior writer ...

Researchers have designed and tested ‘human-centric’ LEDs that emit different wavelengths of blue light depending on whether it’s daytime or nighttime, reducing the disruptive effect artificial light ...

The Internet of things starts at home: Marvell at CES introduces a chipset for networking appliances and LED bulbs wirelessly. Martin LaMonica is a senior writer covering green tech and cutting-edge ...

Along with being brighter, LED bulbs tend to use less power and have a much longer average lifespan compared to conventional halogen bulbs. Now that LED lighting technology has gotten significantly ...

Scientists have been working for years to harvest the power of ambient radio waves to power small devices, and these days there is hardly a richer source of these signals than Wi-Fi networks.

Two NFC-PWM configuration ICs, Infineon’s NLM0011 and NLM0010 enable contactless programming of the driver current for LED lights. Both of these NFC wireless communication devices provide a ...
